I/O type for DP AUX

Hello,

 

Could you advise what I/O type should I use for DisplayPort Auxiliary channel?

 

Thanks,

Vladimir

Re: I/O type for DP AUX

@vyudovich which device are you targeting?

 

For example all the way back in Spartan-6 there was a display_port IO standard that let you interface the AuX channels. 

 

In this case this was a 2.5V/3.3V bi-directional differential signalling interface. My understanding was that this was a very slow link.

 

maybe look at the device you were looking to interface with. 

Also look at the IP guides for this

Re: I/O type for DP AUX

HI @vyudovich

 

FPGA IO-STD used for the half duplex  differential AUX channel  is  LVDS.

you can always generate an example design of a Display port subsystem for KC705  and   check for any implementation details like this.

 

 

Thanks
